Re: Success on 7 deg F motorized bicycle work commute!
I've been commuting on my motorized bicycle for a couple weeks in 20°f weather. Broke an axle on car so I had no choice (fixed car last night). As OP said, its all about the prep.
I owned nothing but bikes/motorcycles in my twenties, no cars. Its a bit extreme, but i rode enduros all thru the Indiana winters, it beats walking anyday.
Now that i have commuted in cars for decades, i forgot how fun/satisfying it is to take on Mother Natures challenges. I might continue to commute on bike when possible.
